ENDLESS TRACKS MOUNTED 0N WHEELED. CARRIERS.

.7 '0 all whom, 2'1, may concern Be it known tl'at I, lmurrn Monro-mun, residing at Fres' o, in the eounty of Fresno and State of (afornizn have invented'some new Deviees for he (onstrnction of Endless Tracks Mounted on 'heeled Carriers, of a'liieh the following is a specification.

y invention relates to improvements in traetion engines of the rharaeter set forth in Patent No. HUJJFOII, granted to me September 10. 190T. and whieh consists of endless traeks and. wheeled rarriers on trneks arranged to travel on the tracks amt provided with means for pieking up and laying down the saute as the engine 'atlvanres.

The principle object. of my present invention is to provide a mechanism of this eharaeter having two independent and parallel endless traeks so' roustrurted that they will he automatieallv laid in ronrentrie eurres when the machine is turned to either side, the. eomplete merhanistn operating with ease and evenness when turning or follow .ing enrves as well as in moving forward in a 'lhese endless. traelts whirhare eompo ed of overlapping tle.\il l v jointed set-lions. are provided with means whieh are arranged to arts reeiprorally in eoiiperation with the trm-h wheels of the ears. so that every sertion of tho laid llttt'k is pressed tirtnly and evenly against the gronml amt produres stilt-- stantial rigid traek ways: and the traelts are also provided with means earried Irv the ears for dist rihutiag evenly the load of the laid traek set-t ions. and with means for halaneing the ears transversely when the meehanism passes over the inequalities of the road.

The endless traeks antl the end ears are also eoiiperat'ivel eotnhined with additional trael; seetious that eonsist. of a. s vstem oftensiou deviees operating at the looped port ns of the endless traelts. and of a system of spring and roller derives for laying down and pin-hing up the traek sertious as re- Specifioatlon of Letters Patent.

jeet matter shown quired. and mean. for gltltling and supporting the endless traelts.

The whole ronstruet ion is arranged as a eomplete merhauism in whit-h all the parts artin eonjunetion with one another and ill the manner to he tleserihed iii a later part of the speeilieation.

Modified t'orms ot' the invention-are also Patented Feb; 13,1912. 595,741.

deseribed and illustrated in the aerompanying drawings, and some of them relate more partieularly to earriers provided with an endless t'raek plaeed in the renter of the marhine, as it is clear and evident that the numher of endless tracks which are used in the construction of this machine does not; materially change the lines of eonstruetion which have been set; forth.

With the foregoing and many other objeets in riew, the invention consists also of rertain combinations and arrangements of parts, and in the details of construction hereinafter fullv described and claimed, and illustrated in tie tlL'Qtll'l|):|ll \lllg drawings, in whiehr- Figure l is a side elevation of a machine of the elass' deserihed embodying my invention.

In the preferred embodiment of my invention illustrated in Fig. 1, I have shown two car bodies 1, which may be of an form and construction, and which are exibly connecfcd at 2.

Each of the cars is shown as sup orted by a single outer truck 3, and by a ouble inner truck, called combination truck 4, which. latter consists briefly of two or more wheeled trucks 5, united to one another by a horizontally extending connectin frame 6 designed to support one of the en 5 of thecar body 1, as will be understood on reference to Figs. 1, 2, 5 and 6. A pair of rubber tired wheels 139 resting on the ground on either side serve to balance each car transversely.

Proceeding now with the detailed description of a combination truck 4, see Figs. 5 and 6, each of its sub-trucks 5, consis of a rectangular truck frame carrying suitable bearings for axles 7, on the end portions of which are arranged track engaging wheels 8 and 9. The wheels 8 are fixed to the axles, but the wheels 9 have enlar cd hub portions which enable them to sli e longitudinally on said axles so that said wheels may adapt themselves 0 the two separate and independent end ess tracks, which may or may not be at the same distance from each other on account of the inequalities that may be encountered on road surfaces. To give clasticity in a. vertical lane to these trucks, and to prevent sharp in ting when they pass over track sections placed on rough or unequal surfaces of the road, (see Figs. 5 and 6), I provide, a pair of springs 10 mounted on the end bars of theframe of each truck 5, and these sprin 10 serve to support opposite transverse firs 11, for a purpose to presently explained. Arranged on the cen-v tral portion of the side-bars of said truck frame are springs 12.supporting the ends an the consecutive directing bars are loosely connected to ther means 15, which will be fully escri hereinafter.

At this point it is necessary to note, that the trucks of this machine are fitted totfio on the straight or curved portions, of e track sections by the combined iiction of the truck flanged wheels, which are fixed.
